A nurse is caring for a client with chronic constipation. Which nursing intervention should be implemented first to promote bowel elimination?

## 보기

1. Encourage increased fluid intake of at least 2-3 liters per day unless contraindicated **✔ 정답**
2. Administer a phosphate enema as prescribed by the physician
3. Insert a rectal suppository to stimulate bowel movement
4. Recommend immediate use of stimulant laxatives for quick relief

**정답: 1**

## 해설

Increasing fluid intake is the priority as it softens stool and promotes natural elimination, addressing the root cause safely. Other interventions like enemas or laxatives are more invasive and should follow after non-invasive measures.

Understanding the Priority Setting Framework

When a nurse is faced with multiple potential interventions for a client with chronic constipation, the NCLEX-RN requires you to prioritize using a framework that ensures client safety and follows the least invasive, most physiologic approach first. The nursing process dictates that independent, low-risk interventions should be implemented before dependent or invasive ones. In this scenario, the correct initial action is to encourage increased fluid intake, as it addresses a fundamental physiologic need with minimal risk.

Why Fluid Intake is the Foundational Intervention

Chronic constipation often results from a combination of factors, including slow colonic transit and inadequate stool hydration. The colon's primary function is to absorb water from the fecal stream. If the body is systemically dehydrated, the colon will absorb maximal fluid, leaving the stool hard, dry, and difficult to pass. By encouraging a fluid intake of 2-3 liters per day (unless contraindicated by cardiac or renal conditions), the nurse helps ensure adequate hydration to keep stool soft and bulky. This is a non-invasive, independent nursing action that targets the underlying physiology of water absorption in the large intestine. It is the safest first step before escalating to pharmacologic or mechanical interventions, which carry risks like electrolyte imbalance, bowel perforation, or dependence .

Analyzing Why Other Options Are Not the Priority

The other options represent a progression to more invasive treatments that should not be the first line of defense for chronic, non-urgent constipation.

- Administering a phosphate enema: This is a dependent nursing intervention requiring a physician's order. It is a more invasive procedure that introduces fluid into the rectum and sigmoid colon to mechanically distend the bowel and stimulate peristalsis. It carries risks, particularly phosphate enemas, which can cause serious electrolyte disturbances (hyperphosphatemia, hypocalcemia) and mechanical trauma to the rectal mucosa. This would be considered only if oral and less invasive methods fail .

- Inserting a rectal suppository: While effective for stimulating evacuation from the lower bowel, this is still a locally invasive procedure that can cause rectal irritation, discomfort, and in rare cases, vagal stimulation leading to bradycardia. It bypasses the body's natural regulatory mechanisms and does not address the systemic issue of hydration that contributes to stool consistency higher in the colon.

- Recommending immediate use of stimulant laxatives: Stimulant laxatives work by chemically irritating the intestinal mucosa to increase peristalsis. Their immediate use is not a first-line approach for chronic constipation due to the risk of dependence, cramping, and electrolyte loss with long-term use. A non-pharmacologic, lifestyle-based intervention like increasing fluids is always the appropriate initial nursing recommendation. This aligns with a nurse-led approach to managing defecation dysfunction, where dietary and fluid modifications are the foundational, first-line strategies before advancing to medications .

Clinical Practice Guide: Prioritizing Interventions for Chronic Constipation

When managing a client with chronic constipation, the nurse must prioritize interventions using a framework that emphasizes safety and the least invasive, most physiologic approach first. Independent nursing actions that address the root cause of hard, dry stool—inadequate hydration—should be implemented before escalating to dependent or invasive procedures.

Step 1: Assess and Implement Foundational, Non-Invasive Measures

- **Increase Fluid Intake:** Encourage 2-3 liters of water per day unless contraindicated by conditions such as heart failure or end-stage renal disease. Adequate hydration is critical to prevent the colon from over-absorbing water from the fecal stream, which leads to hard, dry stool.

- **Promote Dietary Fiber:** Gradually introduce 25-30 grams of fiber daily from fruits, vegetables, and whole grains to add bulk and soften stool. Sudden increases can cause gas and bloating.

- **Facilitate Mobility and Toileting Routine:** Assist with ambulation if safe, as physical activity stimulates peristalsis. Establish a regular toileting schedule, particularly after meals, to capitalize on the gastrocolic reflex.

Step 2: Escalate to Pharmacologic or Mechanical Interventions Only if Conservative Measures Fail

- **Bulk-Forming Laxatives (e.g., psyllium):** These are the next safest option as they mimic dietary fiber, absorbing water to soften stool. They must be taken with sufficient fluid to avoid obstruction.

- **Osmotic Laxatives (e.g., polyethylene glycol):** These draw water into the bowel to soften stool and are generally safe for short-term use. They are preferred over stimulant laxatives for chronic management.

- **Rectal Suppositories or Enemas:** Use only when oral measures are ineffective or rapid relief is needed. These are invasive procedures that require a physician's order for medicated forms and carry risks such as rectal irritation, electrolyte imbalances (phosphate enemas), or bowel perforation.

- **Avoid Immediate Stimulant Laxatives:** Do not recommend stimulant laxatives (e.g., bisacodyl, senna) as a first-line treatment for chronic constipation. Long-term use can lead to cathartic colon syndrome, dependence, and severe electrolyte disturbances.

Key Safety and Prioritization Reminders

- **Least Invasive First:** Always apply the principle of starting with the safest, most physiologic intervention. Fluid and fiber are independent nursing actions with minimal risk.

- **Check for Contraindications:** Before encouraging high fluid intake, verify the client's cardiac and renal status. Before using any laxative or enema, assess for bowel obstruction, acute abdomen, or recent abdominal surgery.

- **Monitor and Document:** Record fluid intake, bowel movement frequency and consistency (using the Bristol Stool Chart), and the client's response to interventions to guide further care.

## 핵심 개념

- **Nursing Process** — A systematic problem-solving framework guiding nurses to implement independent, low-risk interventions before dependent or invasive ones.
- **Colonic Water Absorption** — The large intestine's function of reclaiming water from fecal matter; dehydration leads to maximal absorption and hard, dry stool.
- **Least Invasive Principle** — A prioritization rule in nursing that favors conservative, physiologic interventions with minimal risk over pharmacologic or mechanical procedures.
- **Independent Nursing Intervention** — An action a nurse can initiate without a physician's order, such as encouraging fluid intake, based on professional knowledge and judgment.
- **Stimulant Laxatives** — Medications that induce bowel movements by irritating the intestinal mucosa or stimulating nerves; prolonged use can cause dependence and electrolyte disturbances.
